Am I able to charge this unit with a portable solar power panel & run my laptop on it for at least two hours?

I have used this unit to power my laptop for at least two hours. I am sure you could use a solar charger to increase that time, I believe there are either versions of this type of device that are sold with a solar charger, you cold buy one or make one with parts from amazon.

You should be able to charge it with a solar panel as long as it meets the jumpers charging requirements labeled in the back of jumper. It will run your lap top way more than 2 hours.

I dont think thst you will have to rechage the jump box for several hours if all that you are doing is charging a labtop. I can jump several vehicles that takes a lot more power than a labtop and I only chsrge the box every two to tbree weeks.

It would work the same as it does in the truck for asking as you had the twelve volt battery it was hooked to charge. If you let the solar panel charge your 12v bater all day you should be able to use it for laptop, cellphone charger or small fan up to maybe 12inch fan just check the watts for hay ever you plug up

You can, but it's not a true solar charger. The solar and wind charger are just too keep the battery from dropping in between charges. I contacted k3 they told me to charge the batter on this unit by solar from dead would take 180 -200 hours., with the wind charger would take over 400 hours..

I run mine on a 12 volt battery for 20 hours with no issues, I would think the right solar panel would work.

Have not tried doing that, but it's likely a few long minutes. This is not an instant charger and has a small wattage output. It's designed for a last-resort backup aid, which comes in handy where other sources are out of reach or voltage issues pose risk of damage to your phone, such as in overseas travels.

NO, your laptop won't have enough power. I tried that, it didn't work for me. Make sure you tell them to give you a U.S. adapter if you order it because you will get one from ASIA, if you don't.

Yes. Our setup is consists of the charging panel, an RV battery, and a cigarette-outlet style inverter. With that, we had enough electricity to power our little pick-up camper AND charge cell phones and my laptop on a 3-day camping trip. Without the battery, though, I think you'd pretty much have a trickle charge that would take FOREVER to power up a laptop.

Yes, you can use it, but regarge it before taking to outside. Unfortunately, it does not keep long power supply as characterized by producent.

You would also need a Solar Charge Controller & a Battery. Check YouTube for instructions.

Yes, but it doesn't have a easy off switch, so use the power supply jack as a switch to limit it to of two hours of use.

It's only 17 amp hours so I'd say for 500 watts, about 10 minutes? Probably less? If you want more substantial running time, your best bet is probably to build your own kit with a solar charger battery, where you can usually find 125 amp hours or more, and then get an inverter and charger separately. It'll cost a lot more but 125 amp hours from a 12v battery should power 500 watts for over an hour.

To answer your question, yes, it can run solely on battery power for at least a handful of hours if it's completely charged prior to use. The company recommends a full 24-hour charge before using it for a prolonged period of time, whether it's plugged in or not. If you're just using it for an hour or two, it's fine to keep unplugged, but any longer than that, and I'd say plug it in.

Not really it's going to be a waste of energy . I plugged it 2 hours before using it.

Throwing in my two cents. Get two for this. It'll work fine for awhile for you the way you want to do it, but ultimately, your battery is going to lose charge 'cause you will be running close to max on the panel all things considered unless you are in bright sunlight all the time. Plus, over time, your battery is not going to charge as efficiently. My 100W Grape tests at 5 amps in good sunlight. But then there's nighttime....:-) I run an off grid system, and am going to get a second panel just because of those cloudy days. An MPPT controller will help maximize your charging too. I haven't gotten one of those yet. Throwing in my two cents. Get two for this.

no its not enough to power a laptop, but it might PoWer a 7-inch tablet if you left it out in direct Sun for like 4 hours maybe 6 hours

This will vary wildly on your operating factors. For example, will you have the screen on your laptop on and at what brightness? Will any physical drives be operating or are they SSDs? What processor do you have (older gen Intel i7 chips will shred through the power quickly). Will this also be powering the weather station in any way? What is the temperature and humidity where the unit will be? It becomes a big math equation based on the draw of your connected equipment. Most laptops have a 60-90w power supply, but don't necessarily draw that much at all times. Looking at the manufacturer's provided runtime graph in the product details on Amazon, you can get a rough idea that you would expect well over 90 minutes runtime for a load &lt; 100 watts. I can tell you my desktop computer with i7 chip and LED monitor is showing 122 minutes runtime (untested, unconfirmed) so I would say most laptops would be in the 2-3 hour range.

Yes we can charge using laptop. But I do not think it is holding the charge too much time .
